Not what I get:

regression=# create table tbl1(eventid int);
CREATE TABLE
-- load data
regression=# SELECT eventid FROM tbl1;eventid
--------- 119064 119064  60116  16082  16082  16303  16082  92628  92628  60083
(10 rows)

regression=# create table tbl2(eventid int);
CREATE TABLE
-- load data
regression=# SELECT eventid FROM tbl2;eventid
--------- 123989 123989 123989  16134  16134  16368  16134  92685  92685  60115
(10 rows)

regression=# SELECT eventid FROM tbl1 WHERE eventid NOT IN (SELECT eventid FROM tbl2);eventid
--------- 119064 119064  60116  16082  16082  16303  16082  92628  92628  60083
